Diagnostic Steps

1
Inspect the brake fluid reservoir for low fluid levels.
2
Check for any visible leaks in brake lines, calipers, or master cylinder.
3
Examine brake pads and discs for wear and tear.
4
Inspect the brake booster for any signs of fluid leakage.
5

Solution

1. Preparation

Gather tools and materials: Brake fluid (DOT 4 or as specified), funnel, rags, and gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Locate the Leak

Check the brake fluid reservoir for the current fluid level.
If low, inspect the brake lines from the master cylinder to the wheels for any signs of wear or leaks.
Inspect the brake calipers for any signs of fluid leakage around the seals.
Examine the master cylinder for any signs of internal leakage.

3. Repair the Leak

If a leak is found in the brake line:
- Use a socket set to remove the damaged section of the line.
- Replace with new brake line and secure it using appropriate fittings.
If the leak is in the caliper:
- Remove the wheel using a lug wrench.
- Unbolt the caliper using a socket set, replace the seals if necessary, or replace the caliper if damaged.
If the master cylinder is leaking:
- Disconnect the brake lines using a flare nut wrench.
- Unbolt the master cylinder from the brake booster and replace it with a new one.

4. Refill Brake Fluid

Use a funnel to refill the brake fluid reservoir with the appropriate brake fluid (DOT 4).
Ensure the fluid reaches the "MAX" level mark.

5. Bleed the Brakes

Begin at the wheel farthest from the master cylinder, typically the passenger rear.
Use a brake bleeder kit to bleed the brake lines until no air bubbles are present.
Repeat for each wheel, moving to the driver rear, passenger front, and finally driver front.
Ensure the fluid level remains at "MAX" throughout the bleeding process.
